IMPROVEMENT IN CAR-BRAKE SHOES.

Specification forming part of Letters Patent No. 170,409, dated November23, 1875; application filed July 10, 1875.

To all whom it may concern:

Be it known that I, HENRY STENTZ, of Harrisburg, in the county ofDauphin and in the State of Pennsylvania, have invented certain new anduseful Improvements in Car- Brake Shoe; and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings and to the letters of referencemarked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangementof a brake-shoe for railroad-cars, as will be hereinafter more fully setforth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in whichFigure l is a longitudinal section of my brake-shoe. Fig. 2 is aperspective view of the same. Fig.3 is a perspective view of aconnecting-bolt used therein.

A represents the brake-shoe proper, constructed in any suitable manner,to be attached to the brake bar, and formed with a curved or dovetailedrecess across the front. It has also projecting lips a a. at the top andbottom edges to form bearings for the rubber B. The rubber B is formedon the back with a rounded or dovetailed projection, 11, of such size asto be inserted endwise in the recess on the shoe, and this projection isslotted or grooved longitudinally from the rear side. 0 represents a rodof suitable length, provided with an elongated head, D, at one end, andin the center with an arm or bolt, E, extending from it at right angles.The arm or bolt E is passed through the shoe A in the center of therecess, and fastened by a nut, d, the rod lying on the bottom thereof,and the head D closing one end of said recess. The rubber B is then slidinto the recess over the rod 0, and held by means of a key or othersuitable device on the other end of the rod.

By this means the rubber can easily be removed without lowering thebrake-bar, and the device is simple, cheap, and durable, and not liableto get out of order.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The rod 0, provided with the head D and bolt-arm E, in combination withthe brakeshoe A and removable rubber B, substantially as and for thepurposes hi rein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this6th day of July, 1875.
